In order to provide unified and high effect manage means, we build up theB/S long-distance learning model as teaching model based on xml to make upwith the lack of the current B/S three-layer model, such as the heavy load on theserver, etc.

在教学模型方面，针对目前 B/S 三层数据模型中服务器端负载过重等不足之处，本文构建了基于 XML 的 B/S 网络教学模型，目标是为教学系统提供统一、高效的管理手段。

Methods In order to estimate core temperature T(subscript c from skin temperature T(subscript s, the paper simulated an environmental temperature T(subscript e change. From the change, the paper obtained the thermoresistance ratio of adiabator R(subscript e and body surface tissue R(subscript c, at the same time, deducted environmental temperature T(subscript e influences from the skin temperature T(subscript s. The feasibility and accuracy of the method was tested by a self-made body temperature simulator.

提出通过人为改变环境温度T(下标 e而获得个性化的绝热材料热阻R(下标 e对体表组织热阻R(下标 c比值的途径，实现从皮肤温度T(下标 s中扣除环境温度T(下标 e影响，从而达到从皮肤温度T(下标 s测值中估计体核温度T(下标 c的方案和具体测量方法，并用自行设计的模拟体温发生器对此方案进行了可行性和准确性验证。

The rubbed surface was analyzed with XPS and EPMA, the results shown that the element S, N were as thiadiazole and imidazoline compounds in the rubbed surface film. The tribological properties of surface modified TiO〓 nanoparticles as water base lubrication additive was studied firstly.

用XPS、EPMA对摩擦后的磨斑表面进行了表面形貌，表面膜元素组成，及表面膜中的N〓、S〓电子结合能进行了考察，并与相应母体环化物的N〓、S〓进行了比较，发现摩擦后，磨斑表面膜中的S、N元素，主要是以噻二唑及咪唑啉的形式存在。

A C-C bond type radical initiator i.e. 1,1,2,2-tetraphenyl-1,2-ethanediol and a S-S bond type thermal iniferter, i.e., tetraethyl thiuram disulfide were used to consist of new reverse ATRP initiation systems TPED/FeCl3/PPh3 and TD/FeCl3/PPh3, respectively."Living"/controlled polymerizations of a polar monomer MMA and a non-polar monomer St were investigated with the initiation systems as well as other new initiation systems; behavior of vinyl polymerization with a new asymmetrical C-C bond type thermal monomeric iniferter was studied also.

前者选用C-C键型的自由基聚合引发剂1，1，2，2-四苯基-1，2-乙二醇、S-S键型的热iniferter二硫化四乙基秋兰姆组成新引发体系TPED/FeCl3/PPh3、TD/FeCl3/PPh3，研究这些引发体系引发MMA、 St聚合的&活性&/控制聚合行为，同时研究一些其他新引发体系；后者合成了一种新的非对称C-C键型热引发转移终止剂，并研究其自由基聚合规律。

In English, clear unaspirated stops only in the s-word after the first, and Qing aspirated stops in word-initial, two consonants in a complementary distribution : s-after there is no aspirated stops,...

在英语中，清不送气塞音只出现在词首s-之后（spin、star、scar），而清送气塞音出现在词首（pin、tar、car），两套辅音处于互补分布：s-之后不存在送气塞音，。。。

A type of high-performance fuel-rich propellant for the unchoked ducted rocket has been developed. The burning rates of the fuel-rich propellant are greater then 2mm/s at 0.5MPa, the greatest one is up to 4. 05mm/s. The burning-rate exponent is greater than 0.5, the highest one reaches 0.58. The fuel-rich propellant grain can combust steadily in the gas generator at 0.226MPa. The uniaxial mechanical properties and the processability of the fuel-rich propellant are good.

研制了一类用于非壅塞固体火箭冲压发动机的高性能铝镁贫氧推进剂：0.5MPa下燃速高于2mm/s，最高者达4.05mm/s；燃速压强指数高于0.5，最高者达0.58；直连式实验时，在0.226MPa下燃烧稳定；具有良好的力学性能和工艺性能。

The property S ≈ C being undecidable in general, validators are necessarily incomplete and should reply false if they cannot establish S ≈ C.

通常S≈ C性质是不可判定的，因此验证器必定是不完备的，在无法得到S≈ C时它应该回答&false&。

Our results shown: Compared with those of the unradiated rats, the number of S-100 protein immunoreactive positive glial cells in the brains of the irradiated rats increased gradually. More S-100-positive glial cells with multiple long processes and hypertrophic cell bodies were also observed in these areas.

在此基础上，又做了同一照射剂量（20Gy）照射大鼠半脑后不同存活期间（id，7d；14d，Zld，28d）大鼠全脑S－100动态变化的观察，发现其规律如下：在上述时间点大鼠脑内各部位卜刁m蛋白免疫反应细胞数量进行性增加，伴有 S－100免疫阳性细胞的胞体逐渐增大和交起增多，与正常对照组具有明显的差异。

Occasionally, privileged guests gain access to Mr Ospel's inner sanctum - a large, light, but surprisingly unrevealing office dominated by a giant model of Alinghi, the UBS-sponsored yacht that has twice won sailing's coveted America's Cup.

偶尔，贵宾也会获准进入奥斯佩尔的内室--一个宽敞、明亮但异常普通的办公室，显眼的位置摆着一艘阿灵基号巨型船模--瑞银赞助的这艘帆船曾两度夺得令人艳羡的美洲杯(America's Cup)帆船赛冠军。

this paper discussed several untestable assumptions which were often used in epidemiologi-cal observational studies,and some paradoxical results that may arise under different assumptions were showed.simpson's paradox and lord's paradox were introduced.assumption of treatment assignment in causal inference of epidemiological studies,assumption of control group in evaluation of exposure ef-fects,and assumption of missing data mechanisms in incomplete data analysis were also discussed.

本文主要讨论流行病学观察性研究中几种常用的假定，介绍simpson's悖论和lord's悖论，逆回归问题，以及在不同假定下可能出现的相互矛盾的结果。探讨流行病学研究的因果推断中处理分配机制的假定，暴露作用评价中对照组的模型假定，以及不完全数据分析中缺失数据机制的假定。
